If one or more women complete a Talmudic tractate, can they make a siyum?

Question

There is this related M.Y. question about women joining a men's siyum.

If one or more women complete a Talmudic tractate can / should they make a siyum? I know that women cannot form a minyan, however, everal related questions to the siyum activities:

• Can a woman say the hadran and following paragraphs without a minyan, or should she have a man say it?
• You would need a minyan (10 men) to say the Kaddish at the end. If you have that, can / should the woman say the Kaddish? If not, why would that be a different rule than a woman saying the Mourner's Kaddish in a minyan?
• If you do have a minyan, can the woman recite the ending Mishnah to make the siyum, or should a man do it? Can a man do it if he did not complete or read part of the tractate?
• Considering that if there is a minyan (esp. for Kaddish) that means that there isa mixed crowd, must there be a mechitza (partition) during the recital of the last Mishnah, the hadran and / or the Kaddish?

Answer 1

Harav Beari addresses this question here:
He asks firstly whether it is dependent on the obligation to learn Torah, which is primarily a Mitzva for men (as opposed to children), etc.
He quotes the 'Tzafnad Pa'aneach' who explains why children can make a Siyum, before questioning whether there may be a difference (as children may have more of an obligation).
He quotes 'Shut Minchas Dovid 5-99' who writes that wome don't make a Siyum on completing the Torah, though writes that if one learned something that would help her in her Mitzva observance, then she should make a Siyum on that.

Unfortunately, he doesn't address whether the woman says Kaddish and your other questions.

Answer 2

In the podcast Daf Yomi for Women (soon to be renamed Hadran Daf Yomi for Women), the speaker, Michelle Cohen Farber, does say Hadran at the conclusion of masechtot. She doesn't have a man say it for her and the women who learned with and from her. She does not, as far as I recall, say kaddish because there is presumably not a minyan of men present.

A mechitza is required only for a service containing shmona esrei (shacharit, mincha, maariv, musaf or neila) that meets regularly. An occasional minyan (such as at a wedding for example) does not require a mechitza but only that men & women stand/sit separately rather than mixed. Similarly, a service that doesn't include shmona esrei, such as the wedding itself (the "chuppah" as event) requires that people be seperate, but not a mechitza per se. So a siyum wouldn't require a mechitza.
